Description
Technical field
The present invention relates to in Urban Road Landscapes collection process rainwater Rain Garden system regions, especially one
Plant multi-functional storage and arrange Rain Garden system.
Background technology
Rainwater is the important step in city water cycle system, to regulation, supplements regional water, improvement ecology
Environment plays extremely crucial effect.In the quickly promotion of urbanization process, due to turning of Land-Use
Become and the replacement of natural terrain is caused urban morphology to there occurs great variety, urban rainwater problem by hardening earth's surface
More show especially out, storm runoff the city surface source pollution caused has caused the great attention of international community.Rain
Arise at the historic moment as a kind of municipal landscape technique tackling rainfall runoff in spray garden.Rain Garden is a kind of effective
Rainwater self-purification and disposal technology, be also a kind of biological delay facility.Typically it build the region that physical features is relatively low in,
Early-stage rainwater, the rainwater simultaneously confluxed by little area is purified by natural soil or replacing Artificial Soil and planting plants
Temporarily it is detained and the most slowly penetrates into soil, to reduce run-off.It is low because having expenditure of construction, operational management letter
Single, natural beauty, the advantage such as be easily combined with view and be widely used.
At present, the draining of city inside road is all to be realized by gully and the gutter arranged on road,
But when rainfall is bigger, less timely by draining quantitative limitation draining, can cause road surface that ponding occurs,
Affect the traffic circulation on road surface；The greenbelt being much made up of it is provided with kerbstone, in greenbelt on road
Turf plant or other plant play greening, clean air, the effect of collection rainwater, but greenbelt is only
The rainwater fallen in greenbelt can be absorbed, and have no idea to help discharge to eliminate the ponding on road surface；Rain
Spray garden is also applied in Urban Road Landscapes, to absorb the ponding eliminating ground, carries out rainwater effectively
Purify, filter, it is achieved the rainwater management of ecological sustainability and rainwater utilization, simultaneously beautifying city.
But, for the area that many is rainy, owing to rainfall is big and contains substantial amounts of organic dirt in rainfall runoff
Dye thing, runoff velocity is relatively big, and souring is obvious.When entering Rain Garden, rainwater containing a large amount of rainfall runofves
Garden limited filtering capacity, causes flow velocity to decline, and resistance to water-flow increases, and sludge settling, is stranded in Rain Garden,
Accumulate over a long period and Rain Garden water purification ability and digestion capability will be caused to decline, be unfavorable for rainwater get rid of in time and
Effectively utilize.
Summary of the invention
The technical problem to be solved is for above-mentioned deficiency of the prior art, it is provided that a kind of many merits
